 Agreement 

Section 1. Board Observation Rights. 

(a) During the period commencing upon the execution and delivery of this Agreement and ending on the Board Rights Termination Date (defined
below), the Crestwood Entities shall grant the Purchasers, collectively, the option and right, exercisable, upon written approval of a majority of the then outstanding Preferred Units held, directly or indirectly, by the Purchasers (in the
aggregate), by delivering a written notice signed by such Purchasers of such appointment to the Crestwood Entities (the “Observer Notice”), to appoint a single representative, who shall be employed by one of the Purchasers (or their
Affiliates) at the time of such appointment (the “Board Observer”), to attend all meetings (including telephonic) of the full Board in an observer capacity. The Observer Notice shall be delivered to the Crestwood Entities prior to
the Board Observer’s attendance of any meeting of the full Board. The Board Observer shall not constitute a member of the Board and shall not be entitled to vote on, or consent to, any matters presented to the Board. For the avoidance of doubt,
the Board Observer shall have no right to attend any meeting of any committee of the full Board (each, a “Committee”); provided, however, the Crestwood Entities shall (i) give the Board Observer written notice of
the applicable meeting or action taken by written consent of such Committee at the same time and in the same manner as notice is given to the members of such Committee and (ii) with respect to the Audit Committee and the Compensation Committee
of the Board, provide the Board Observer with copies of all written materials and other information (including, without limitation, copies of minutes of meetings or written consents of such Committee) given to the members of the Audit Committee and
the Compensation Committee in connection with such meetings or actions taken by written consent at the same time such materials and information are furnished to such members of the Audit Committee and the Compensation Committee. 

(b) The Crestwood Entities shall (i) give the Board Observer written notice of the applicable meeting or action taken by written consent
at the same time and in the same manner as notice is given to the members of the Board, (ii) provide the Board Observer with copies of all written materials and other information (including, without limitation, copies of minutes of meetings or
written consents of the full Board) given to the members of the Board in connection with such meetings or actions taken by written consent at the same time such materials and information are furnished to such members of the Board, and
(iii) provide the Board Observer with all rights to attend (whether in person or by telephone or other means of electronic communication as solely determined by the Board Observer) such meetings as a member of the Board. The Board Observer
shall agree to maintain the confidentiality of all non-public information and proceedings of the Board and to enter into, comply with, and be bound by, in all respects, the terms and conditions of a confidentiality agreement, substantially in the
form attached hereto as Annex A (the “Confidentiality Agreement”); provided, however, upon request from a Purchaser or such Purchaser’s Affiliates, the Board Observer shall provide, on a confidential basis, such
non-public material and information to such Purchaser and their Affiliates; provided that such Purchaser and their Affiliates have agreed to comply with and be bound by, in all respects, the Confidentiality Agreement. For the avoidance of
doubt, the recipient of such confidential information from the Board Observer (whether a Purchaser or a Purchaser Affiliate) may further provide such information to (i) any other Purchaser or Purchaser Affiliate and (ii) any legal counsel
that has been engaged by such recipient to discuss such matters or information; provided, that any such 






 
recipient in clause (i) or (ii) agrees and acknowledges in writing that they are bound by the provisions of the Confidentiality Agreement. For purposes of this Agreement,
“Affiliates” shall have the same meaning ascribed therefor in the Purchase Agreement. Notwithstanding any rights to be granted or provided to the Board Observer hereunder, the Crestwood Entities reserve the right to exclude the
Board Observer from access to any material or meeting or portion thereof if the Board reasonably determines, in good faith, that such access would (A) prevent the members of the Board from engaging in attorney-client privileged communication or
(B) result in a conflict of interest with any Purchaser; provided, however, that such exclusion shall be limited to the portion of the material and/or meeting that is the basis for such exclusion and shall not extend to any
portion of the material and/or meeting that does not involve or pertain to such exclusion. The Purchaser then employing the Board Observer agrees to indemnify the Crestwood Entities from any and all costs, losses, liabilities, damages, or expenses
of any kind or nature whatsoever arising from the breach by the Board Observer of the confidentiality obligations under the Confidentiality Agreement or this Section 1. 

(c) The rights contained in this Section 1 shall immediately cease and terminate on the earlier of such date (such earlier date,
the “Board Rights Termination Date”) as the Purchasers and their respective Affiliates no longer own (i) at least 75% of the Purchased Units (as defined in the Purchase Agreement) or (ii) a number of Preferred Units,
which, if they were converted into Common Units at the then applicable Conversion Ratio (as defined in Amendment No. 3), subject to appropriate adjustments for splits, combinations and other similar transactions, would be equal to 5% or more of
the total number of Common Units then outstanding. From and after the Board Rights Termination Date, the rights of the Purchasers in Sections 1(a) and 1(b) shall cease. 

Section 2. Board Designation Rights. 

(a) If the Class A Preferred Distribution Amount (as such term is defined in Amendment No. 3) is not paid in full in cash to the
holders of outstanding Preferred Units (as such term is defined in Amendment No. 3) for two consecutive calendar quarters that commence after the Initial Distribution Period (as defined in Amendment No. 3) (such failure, the
“Designation Right Triggering Event”), then, until the Designation Right Termination Event (defined below), the Purchasers shall have the option and right, exercisable, upon written approval of a majority of the then outstanding
Preferred Units held, directly or indirectly, by the Purchasers (in the aggregate), by delivering a written notice of such designation to the Crestwood Entities, to designate one person to serve on the Board (the “Purchaser Designated
Director”) and the Crestwood Entities shall take all actions necessary or advisable to effect the foregoing; provided, however, that such Purchaser Designated Director shall, in the reasonable judgment of the General Partner,
(i) have the requisite skill and experience to serve as a director of a public company, (ii) not be prohibited from serving as a director pursuant to any rule or regulation of the Securities and Exchange Commission (the
“Commission”) or any national securities exchange on which the Partnership’s Common Units are listed or admitted to trading, and (iii) not be an employee or director of any Competitor (as defined below). For purposes of
the immediately preceding sentence the term “Competitor” shall mean any person or entity that (a) is an operating company (and not a financial institution) and (b) engages in the midstream energy business or otherwise
provides similar services or engages in similar business as the Partnership. The Purchasers agree upon the Partnership’s request to timely provide the Partnership with accurate and complete 






 
information relating to the Purchaser Designated Director as may be required to be disclosed by the Partnership under the Securities and Exchange Act of 1934, as amended (the “Exchange
Act”) and the rules and regulations promulgated thereunder. Prior to a Designation Right Termination Event (as defined below), the Purchaser Designated Director may be removed or replaced by the Purchasers at any time and by Crestwood
Midstream Holdings LP, the sole member of the General Partner, for “cause” (as defined below), but not by any other Party; and any vacancy occurring by reason of the death, disability, resignation, removal or other cessation of a
person serving as Purchaser Designated Director, shall be filled solely by the Purchasers. As used herein, “cause” means that the Purchaser Designated Director (i) is prohibited from serving as a director under any rule or regulation
of the Commission or any national securities exchange on which the Partnership’s Common Units are listed; (ii) while serving as the Purchaser Designated Director is convicted by a court of competent jurisdiction of a felony; (iii) a
court of competent jurisdiction has entered, a final, non-appealable judgment finding the Purchaser Designated Director liable for actual fraud or willful misconduct against the Partnership (including, but not limited to, intentionally or wilfully
failing to observe the obligation of confidentiality contained in Section 1(b) of this Agreement); (iv) is determined to have acted intentionally or in bad faith in a manner that results in a material detriment to the assets,
business or prospects of the Partnership or (v) is terminated, removed or resigns for any reason from his or her position, if any, with any such Purchaser at which the Purchaser Designated Director is then employed. Any action by the Purchasers
to designate, remove or replace a Purchaser Designated Director shall be evidenced in writing furnished to the Crestwood Entities, shall include a statement that the action has been approved by the Purchasers and shall be executed by or on behalf of
the Purchasers. While serving as a Purchaser Designated Director, a Purchaser Designated Director (i) shall be entitled to vote on any matter on which independent members of the Board are entitled to vote on (unless prohibited by the rules and
regulations of the Securities and Exchange Commission or the New York Stock Exchange), provided, however, in connection with any matter that could adversely affect the rights, powers, privileges, preferences, duties or obligations of the
Preferred Units, the Purchaser Designated Director shall consult with all Purchasers that hold, directly or indirectly, then outstanding Preferred Units, prior to such Purchaser Designated Director approving such matter in his or her capacity as a
Board member; and (ii) shall be entitled to compensation commensurate with that of an independent member of the Board and reimbursed for reasonable expenses. 

(b) Upon payment by the Partnership to the Purchasers of all accrued but unpaid distributions on the Preferred Units then outstanding (a
“Designation Right Termination Event”), the right of the Purchasers to designate a Purchaser Designated Director shall automatically terminate and the Purchasers shall cause the Purchaser Designated Director then serving as a member
of the Board, promptly upon (and in any event within two (2) Business Days following) receipt of a written request from the Partnership, to resign as a member of the Board. If the Purchaser Designated Director does not resign upon such request,
then a majority of the other director(s) then serving on the Board may remove the Purchaser Designated Director as a member of the Board. 

Section 3. Limitation of Liability; Indemnification; Business Opportunities. 

(a) At all times while the Purchaser Designated Director is serving as a member of the Board, and following any such Purchaser Designated
Director’s death, resignation, removal or other cessation as a director in such former Purchaser Designated Director’s capacity as a former 






 
director, the Purchaser Designated Director shall be entitled to (i) the same modification and restriction of traditional fiduciary duties, (ii) the same safe harbors for resolving
conflicts of interest transactions and (iii) all rights to indemnification and exculpation, in each case, as are then made available to any other member of the Board. 

(b) For the avoidance of doubt, the Board Observer shall have (i) no fiduciary duty to the Crestwood Entities or to any Limited Partner
(as defined in the Partnership Agreement) and (ii) no obligations to the Crestwood Entities under this Agreement, except as described in Section 1 of this Agreement, or to any Limited Partner. 

(c) At all times while the Purchaser Designated Director is serving as a member of the Board or the Board Observer is serving in such capacity
in accordance with Section 1 of this Agreement, such Purchaser Designated Director or Board Observer, the Purchasers and their respective Affiliates may engage in, possess an interest in, or trade in the securities of, other business
ventures of any nature or description, independently or with others, similar or dissimilar to the business of the Crestwood Entities, and the Crestwood Entities, the Board and their Affiliates shall have no rights by virtue of this Agreement in and
to such independent ventures or the income or profits derived therefrom, and the pursuit of any such venture, even if competitive with the business of the Crestwood Entities, shall not be deemed wrongful or improper. None of the Purchaser Designated
Director, the Board Observer, the Purchasers or their respective Affiliates shall be obligated to present any investment opportunity to the Crestwood Entities even if such opportunity is of a character that the Crestwood Entities or any of their
respective subsidiaries might reasonably be deemed to have pursued or had the ability or desire to pursue if granted the opportunity to do so, and each of the Purchaser Designated Director, the Board Observer, the Purchasers or their respective
Affiliates shall have the right to take for such person’s own account (individually or as a partner or fiduciary) or to recommend to others any such investment opportunity. Notwithstanding the foregoing, the Purchaser Designated Director and
the Board Observer shall be subject to, and comply with, the requirement to maintain confidential information pursuant to this Agreement. 

(d) The Crestwood Entities shall purchase and maintain (or reimburse the Purchaser Designated Director for the cost of) insurance
(“D&O Insurance”), on behalf of the Purchaser Designated Director, against any liability that may be asserted against, or expense that may be incurred by, such Purchaser Designated Director in connection with Crestwood
Entities’ activities or such Purchaser Designated Director’s activities on behalf of the Crestwood Entities, regardless of whether the Crestwood Entities would have the power to indemnify such Purchaser Designated Director against such
liability under the provisions of the Partnership Agreement or the First Amended and Restated Limited Liability Company Agreement of the General Partner (the “GP LLC Agreement. Such D&O Insurance shall provide coverage commensurate
with that of an independent member of the Board. 
 (e) For the avoidance of doubt, the Purchaser Designated Director shall constitute an
“Indemnitee,” as such term is defined under the Partnership Agreement and the GP LLC Agreement. 






 Section 4. Standstill. 

(a) During the period commencing on the Initial Closing Date and ending on the third anniversary thereof, without the prior written consent of
the Partnership (provided that such consent shall not be required in the event of fraud or gross negligence on the part of the Partnership or the General Partner), the holders of Preferred Units and their Affiliates will not, directly or indirectly:

 (i) Enter into any transaction the effect of which would be to “short” any securities of the Partnership; 

(ii) Call (or participate in a group calling) a meeting of the limited partners of the Partnership for the purpose of removing
(or approving the removal of) the General Partner as the general partner of the Partnership and/or electing a successor general partner of the Partnership; 

(iii) “Solicit” any “proxies” (as such terms are used in the rules and regulations of the Commission) or
votes for or in support of (A) the removal of the General Partner as the general partner of the Partnership or (B) the election of any successor general partner of the Partnership, or take any action the direct effect or purpose of which
would be to induce limited partners of the Partnership to vote or provide proxies that may be voted in favor of any action contemplated by either of sub-clauses (A) or (B) of this Section 4(a)(iii); 

(iv) Seek to advise or influence any person (within the meaning of Section 13(d)(3) of the Exchange Act) with respect to
the voting of any limited partner interests of the Partnership in connection with the removal (or approving the removal) of the General Partner as the general partner of the Partnership and/or the election of a successor general partner of the
Partnership; 
 (v) Issue, induce or assist in the publication of any press release, media report or other publication in
connection with the potential or proposed removal of the General Partner as the general partner of the Partnership and/or the election of a successor general partner of the Partnership; 

(vi) Instigate or encourage any third party to do any of the foregoing; or 

(vii) If the General Partner is removed as the general partner of the Partnership, participate in any way in the management,
ownership and/or control of the managing general partner or the successor general partner’s operation of the Partnership, other than participation by a Purchaser Designated Director or Board Observer, as described in Sections 1 and
2 of this Agreement. 
 (b) Notwithstanding anything to the contrary in this Agreement, (i) the foregoing shall not in any way
limit the right of the Purchasers or their Affiliates to vote their limited partner interests in the Partnership at any meeting of limited partners of the Partnership so long as there has been no breach of Section 4(a) of this Agreement;
and (ii) for purposes of Section 4(a) of this Agreement, “Affiliates” of GSO COF II Holdings Partners LP shall include any fund managed or advised by GSO Capital Partners LP or its Affiliates; provided,
however, that, in each such case, such fund falls within the credit business of The Blackstone Group LP.

and exclusive statement of the agreement and understanding of the Parties hereto in respect of the subject matter contained herein. There are no restrictions, promises, warranties or undertakings other than those set forth or referred to herein with

specific or similar items or matters immediately following it. Whenever any determination, consent or approval is to be made or given by a Party, such action shall be in such Party’s sole discretion, unless otherwise specified in this
Agreement. If any provision in this Agreement is held to be illegal, invalid, not binding or unenforceable, (i) such provision shall be fully severable and this Agreement shall be construed and enforced as if such illegal, invalid, not binding
or unenforceable provision had never comprised a part of this Agreement, and the remaining provisions shall remain in full force and effect and (ii) the Parties hereto shall negotiate in good faith to modify this Agreement so as to effect the

federal or state court located within the State of Delaware over any such action. Each of the Parties hereby irrevocably waives, to the fullest extent permitted by applicable Law, any objection that it may now or hereafter have to the laying of
venue of any such dispute brought in such court or any defense of inconvenient forum for the maintenance of such dispute. Each of the Parties hereto agrees that a judgment in any such dispute may be enforced in other jurisdictions by suit on the
judgment or in any other manner provided by Law. 
 (e) Waiver of Jury Trial. EACH OF THE PARTIES TO THIS AGREEMENT HEREBY WAIVES, AND
AGREES TO CAUSE ITS AFFILIATES TO WAIVE, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (i) ARISING UNDER THIS AGREEMENT OR (ii) IN ANY WAY CONNECTED WITH OR RELATED OR
INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO IN RESPECT OF THIS AGREEMENT OR ANY OF THE TRANSACTIONS RELATED HERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY OR OTHERWISE. EACH OF THE PARTIES
TO THIS AGREEMENT HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT THE PARTIES TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OF A COPY OF THIS AGREEMENT
WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY. 
 (f) No Waiver;
Modifications in Writing. 
 (i) Delay. No failure or delay on the part of any Party in exercising any right,
power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy. The remedies
provided for herein are cumulative and are not exclusive of any remedies that may be available to a Party at law or in equity or otherwise. 

(ii) Specific Waiver. Except as otherwise provided herein, no amendment, waiver, consent, modification or termination of
any provision of this Agreement shall be effective unless signed by each of the Parties hereto affected by such amendment, waiver, consent, modification or termination. Any amendment, supplement or modification of or to any provision of this
Agreement, any waiver of any provision of this Agreement and any consent to any departure by a Party from the terms of any provision of this Agreement shall be effective only in the specific instance and for the specific purpose for which made or
given. Except where notice is specifically required by this Agreement, no notice to or demand on a Party in any case shall entitle such Party to any other or further notice or demand in similar or other circumstances. Any investigation by or on
behalf of any Party shall not be deemed to constitute a waiver by the Party taking such action of compliance with any representation, warranty, covenant or agreement contained herein. 






 (g) Execution in Counterparts. This Agreement may be executed in any number of
counterparts and by different Parties hereto in separate counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute one and the same
agreement. 
 (h) Binding Effect; Assignment. This Agreement will be binding upon and inure to the benefit of the Parties hereto and
their respective successors and permitted assigns, but will not be assignable or delegable by any Party hereto without the prior written consent of each of the other Parties; provided, that the terms and provisions of this Agreement shall not
be effective or binding upon a Purchaser that has transferred all of its Preferred Units to a third-party and, upon such transfer, the rights of such Purchaser under this Agreement shall terminate and cease. 

(i) Independent Counsel. Each of the Parties acknowledges that it has been represented by independent counsel of its choice throughout
all negotiations that have preceded the execution of this Agreement and that it has executed the same with consent and upon the advice of said independent counsel. Each Party and its counsel cooperated in the drafting and preparation of this
Agreement and the documents referred to herein, and any and all drafts relating thereto will be deemed the work product of the Parties and may not be construed against any Party by reason of its preparation. Accordingly, any rule of Law or any legal
decision that would require interpretation of any ambiguities in this Agreement against the Party that drafted it is of no application and is hereby expressly waived. 

(j) Specific Enforcement. Each of the Parties acknowledges and agrees that monetary damages would not adequately compensate an injured
Party for the breach of this Agreement by any Party, that this Agreement shall be specifically enforceable and that any breach or threatened breach of this Agreement shall be the proper subject of a temporary or permanent injunction or restraining
order without a requirement of posting bond. Further, each Party hereto waives any claim or defense that there is an adequate remedy at law for such breach or threatened breach. 

(k) Transfer of Board Rights; Aggregation. The option and right to appoint a Board Observer or Purchaser Designated Director granted to
the Purchasers by the Partnership under Sections 1 and 2, respectively, of this Agreement, may be transferred or assigned by any Purchaser to one or more of its Affiliates, subject to the transfer restrictions provided in
Section 4.7(d) of the Partnership Agreement, provided, however, that (a) the Partnership is given written notice prior to any said transfer or assignment, stating the name and address of each of the transferee or assignee and
identifying the securities with respect to which such rights are being transferred or assigned and (b) each such transferee or assignee assumes in writing responsibility for its portion of the obligations of such Purchaser under this
Agreement. All Preferred Units held or acquired by Persons (as defined in the Partnership Agreement) who are Affiliates of one another shall be aggregated together for the purpose of determining the availability of any rights and applicability
of any obligations under this Agreement. 






 (l) Further Assurances. Each of the Parties hereto shall, from time to time and without
further consideration, execute such further instruments and take such other actions as any other Party hereto shall reasonably request in order to fulfill its obligations under this Agreement to effectuate the purposes of this Agreement.

Dear Ladies and Gentlemen:

Delaware limited liability company (“Magnetar”), GSO COF II Holdings Partners LP, a Delaware limited partnership (“GSO”) and GE Structured Finance, Inc., a Delaware corporation (“GE” and, together
with Magnetar and GSO, the “Purchasers”), the Purchasers have exercised their right to appoint the undersigned as an observer (the “Board Observer”) to the board of directors of the General Partner (the
“Board”), although the individual serving as the Board Observer may be changed from time to pursuant to the terms of the Board Representation and Standstill Agreement and upon such other individual signing a confidentiality
agreement in substantially the form hereof. The Board Observer acknowledges that at the meetings of the Board and at other times the Board Observer may be provided with and otherwise have access to non-public information concerning the Crestwood
Entities and their Affiliates. Capitalized terms used but not otherwise defined herein, shall have the respective meanings ascribed therefor in the Board Representation and Standstill Agreement. In consideration for and as a condition to the
Crestwood Entities furnishing access to such information, the Board Observer hereby agrees to the terms and conditions set forth in this letter agreement (the “Agreement”): 

1. As used in this Agreement, subject to Paragraph 3 below, “Confidential Information” means any and all non-public financial
or other non-public information concerning the Crestwood Entities and their Affiliates that may hereafter be disclosed to the Board Observer by the Crestwood Entities, their Affiliates or by any of their directors, officers, employees, agents,
consultants, advisors or other representatives (including financial advisors, accountants or legal counsel) (the “Representatives”) of the Crestwood Entities, including, without limitation, all notices, minutes, consents, materials,
ideas or other information (to the extent constituting information concerning the Crestwood Entities and their Affiliates that is non-public financial or other non-public information) provided to the Board Observer. 






 2. Except to the extent permitted by this Paragraph 2 or by Paragraph 3 or 4, the Board Observer
shall keep such Confidential Information strictly confidential; provided, that the Board Observer may, upon request from a Purchaser or such Purchaser’s Affiliates, share Confidential Information with such Purchaser or such
Purchaser’s Affiliates so long as such individuals or entities agree to comply with, and be bound by, in all respects, the terms of this Agreement. For the avoidance of doubt, the recipient of such Confidential Information from the Board
Observer may further provide such Confidential Information to (i) any other Purchaser or Purchaser Affiliate and (ii) any legal counsel that has been engaged by such recipient to discuss such matters or Confidential Information; provided,
that any such recipient in clause (i) or (ii) above agrees and acknowledges in writing to be bound by the terms of this Agreement. The Board Observer may not record the proceedings of any meeting of the Board by means of an electronic
recording device. 
 3. The term “Confidential Information” does not include information that (i) is or becomes generally
available to the public other than (a) as a result of a disclosure by the Board Observer in violation of this Agreement or (b) in violation of a confidentiality obligation to the Crestwood Entities known to the Board Observer, (ii) is
or becomes available to the Board Observer on a non-confidential basis from a source not known to have an obligation of confidentiality to the Crestwood Entities, (iii) was already known to the Board Observer at the time of disclosure, or
(iv) is independently developed by the Board Observer without reference to any Confidential Information disclosed to the Board Observer. 

4. In the event that the Board Observer is legally required or compelled to disclose the Confidential Information, the Board Observer shall use
reasonable best efforts, to the extent permitted and practicable, to provide the Crestwood Entities with prompt prior written notice of such requirement so that the Crestwood Entities may seek, at such entities sole expense and cost, an appropriate
protective order. If in the absence of a protective order, the Board Observer is nonetheless legally required or compelled to disclose Confidential Information, the Board Observer may disclose only the portion of the Confidential Information or
other information that it is so legally required or compelled to disclose. 
 5. All Confidential Information disclosed by the Crestwood
Entities or their Representatives to the Board Observer is and will remain the property of the Crestwood Entities, so long as such information remains Confidential Information. 

6. It is understood and acknowledged that neither the Crestwood Entities nor any Representative makes any representation or warranty as to the
accuracy or completeness of the Confidential Information or any component thereof. 
 7. It is further understood and agreed that money
damages would not be a sufficient remedy for any breach of this Agreement by the Board Observer and that the Crestwood Entities shall be entitled to seek specific performance or any other appropriate form of equitable relief as a remedy for any such
breach in addition to the remedies available to the Crestwood Entities at law. 
 8. This Agreement is personal to the Board Observer, is not
assignable by the Board Observer and may be modified or waived only in writing. This Agreement is binding upon the parties hereto and their respective successors and assigns and inures to the benefit of the parties hereto and their respective
successors and assigns. 






 9. If any provision of this Agreement is not enforceable in whole or in part, the remaining
provisions of this Agreement will not be affected thereby. No failure or delay in exercising any right, power or privilege hereunder operates as a waiver thereof, nor does any single or partial exercise thereof preclude any other or further exercise
thereof or the exercise of any other right, power or privilege hereunder. 
 10. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE, WITHOUT GIVING EFFECT TO ANY CHOICE OR CONFLICT OF LAW PROVISION (WHETHER OF THE STATE OF DELAWARE OR ANY OTHER JURISDICTION) THAT WOULD CAUSE THE APPLICATION OF THE LAWS OF ANY JURISDICTION OTHER
THAN THE STATE OF DELAWARE. 
 11. This Agreement and all obligations herein will automatically expire three (3) years from the date
the Board Observer ceases to act as Board Observer. 
 12. This Agreement may be executed in one or more counterparts, each of which will be
deemed to be an original copy of this Agreement, and all of which, when taken together, will constitute one and the same agreement. The exchange of copies of this Agreement and of signature pages by facsimile or electronic transmission constitutes
effective execution and delivery of this Agreement as to the parties and may be used in lieu of the original Agreement. Signatures of the parties transmitted by facsimile or electronic transmission will be deemed to be their original signatures for
any purpose whatsoever.
